Project Title: Houdini's Bathtub

Purpose: To find whether fuel cubes or solar heating was more efficent or practical in heating water to 100 degrees fahrenheit.

Experimental method:
1.Calculate the amount of energy needed to heat a bin of tap water to desired temperature in BTUs (28 pints, 100-108 Fahrenheit)
2.Design a system for each heating systema.Use camping stove that runs on fuel cubesb.Design solar heating systemi.Spray-paint (or use paintbrushes to paint) a panel of insulation foil blackii.Insert foil into window frameiii.Stuff tubing into window frameiv.Insert end of tubing into pumpv.Insert thermometervi.Spray foam on to seal it invii.Fill bin with water and place pump inside the binviii.Put the other end of tube inside the other end of the binix.Place the solar heating system to a sunny areax.Test the system
